DETAILED DESCRIPTION OF THE EMBODIMENTS

While the invention is susceptible to embodiments in many different forms, there are shown in the drawings and will described herein, in detail, the preferred embodiments of the present invention. It should be understood, however, that the present disclosure is to be considered an exemplification of the principles of the invention and is not intended to limit the spirit or scope of the invention and the embodiments illustrated.

Referring now to FIGS. 1 a and 1 b, in accordance to an embodiment of the present invention, there is illustrated a finger nail polishing device 10 that includes an arm mechanism 15, an adjustable hand rest 20 and a base 25. In this embodiment, the device 10 uses servos and/or motors to move a series of linkages included in the arm mechanism 15 via preprogrammed content to direct a brush 30 to execute a series of brush strokes to paint or polish a user's nails. While an embodiment herein may be described as utilizing servos, it is understood that the utilization of motors or other similar driving components would not alter the scope of the invention.

The hand rest 20 includes a first positioning groove 35 for finger placement and a second positioning groove 40 for thumb placement. Sensors 45 at the base of each groove are triggered when a finger or thumb is positioned in either groove, respectively. Triggering one of two sensors 45 sends a signal to an integrated circuit (IC) to prompt an IC response for facilitation of the preprogrammed content (described below) to direct the servos and linkages to move the brush 30. While this embodiment includes three linkages and four servos, a plurality of linkages and servos may be used to move the brush 30.

Now referring to FIGS. 2 a-2 f, a base servo 50 is housed within the base 25 and is rotatably attached to a cap 55 such that powering the base servo 50 rotates the cap 55 in a clockwise or counterclockwise direction as desired. The cap 55 is further secured to the arm mechanism 15. As such, rotation of the cap 55 rotates the arm mechanism 15 attached thereto.

The cap 55 houses a first servo 60 fixed to the cap 55 and rotatably attached to one end of a first linkage 65 with a threaded port 70 to receive a first servo gear 75 to rotate the first linkage 65 when the first servo 60 is powered in either direction. A second servo 80 is housed within the other end of the first linkage 65 and is fixed thereto. The second servo 80 is rotatably attached to one end of a second linkage 85 and includes a threaded port 90 to receive a second servo gear 95 to rotate the second linkage 85 when the second servo 80 is powered in either direction. A third servo 100 is housed within the other end of the second linkage 85 and is fixed thereto. The third servo 100 is rotatably attached to a third linkage 105 with a threaded port 110 to receive a third servo gear 115 to transfer rotation to the third linkage 105 when the third servo 100 is powered in either direction. The third linkage also includes a threaded port to receive varying attachments, here shown as a brush. The brush 30 moves in accordance with the rotation of the third linkage 105 to facilitate actions such as brush strokes for polishing a finger nail. Other examples of attachments for use with the device 10 include a nail filer and nail buffer. Each of the different attachments may use any number of reomveable connecting means known in the art without deviating from the scope of the present invention.

A polishing action is shown in FIGS. 3 a-3 c. To initiate the polishing action, the IC directs power to the base servo 50 to rotate the cap 55 in either a clockwise or counterclockwise direction to position the brush 30 in line with a polish receptacle 120. The IC then directs power distribution to the servos to position the arm mechanism 15 to dip the brush 30 into the receptacles 120 as seen in FIG. 3 a. In addition to including nail polish in the receptacle 120, various liquids may be used without departing from the scope of this invention, such as nail strengthener. The size and positioning of the receptacles may also vary as the programming included in the IC may direct the arm mechanism 15 to dip the brush 30 in any number of receptacle 120 size variations and locations. Once the brush 30 is dipped in polish, the servos power in accordance to preprogrammed content to move the linkages to position the brush 30 above the finger or thumb positioned on the hand rest 20 as shown in FIGS. 3 b and 3 c. The IC then directs the brush 30 to execute a series of brush strokes to apply the polish to the nail. A targeting means may also be included for fine tuning the positioning of the brush 30 in relation to the nail. For example, a targeting light (not shown) secured to the brush 30 can direct a user to adjust the finger positioning by using light to indicate the path of the brush strokes. As such, users with varying sizes of fingers or nails may assist the device 10 in successfully polishing the desired area of the nail.

Referring now to FIGS. 4 a and 4 b, the hand rest 20 includes the positioning grooves and sensors 45 as described above. Further, the hand rest 20 may adjust in a vertical direction (vertical adjustability not shown) and about an axis 125 to a user's desired hand positioning. A stem 130 is fixed to the base 25 and is rotatably to the hand rest 20 such that the hand rest rotates about an axis 125. The stem 130 may also have a telescoping capability for vertical adjustments.

Referring now to FIG. 5, there is shown a block diagram provided for an embodiment of the device 10. When one of the sensors 45 are triggered in response to the positioning of a user's finger or thumb (or preprogrammed content) a signal is sent via an electrical connection 145 to an IC 150 included in the device 10. The IC 150 contains a processor(s) 155 and a memory 160. The processor(s) 155 accesses preprogrammed signals and/or audio content stored on the memory 160 in the IC 150. The IC 150 further includes programming and electronic components to facilitate and direct audio content and control signals. The processor(s) 155 access the preprogrammed signals and/or audio content based on a program and/or in accordance to a user's input. The processor(s) 155 then generates a response that includes signals and may be in the form of audio or control signals. The IC 155 is in communication with each of the servos. From the processor(s) 155, audio signals may be transferred to an amplifier and speaker (not shown) while control signals are transferred to the servos to power in the desired direction. Further, as the servos are powered, movement is transferred to the linkages as described herein. Additionally, signals may be transferred to a targeting device (not shown) for activation. As a user triggers one or more of the plurality of sensors, the device 10 responds thereto and executes a nail polishing action while audio is played from the speaker, via audio content received by the amplifier. A power supply 165 is included in the device 10 to supply power where necessary. It should further be contemplated that the device 10 may have buttons in communication with the IC 155 to direct movement of the arm mechanism 15 without triggering the sensors.

In the first embodiment, the device 10 includes a means to move the plurality of linkages in accordance to a variety of preprogrammed responses triggered by sensors.

Further and in accordance with the first embodiment, the device 10 includes a means to paint and/or polish a user's nails in accordance to a variety of preprogrammed responses triggered by sensors.

The first embodiment of the device 10 also includes a means to prompt a user to adjust the positioning of a user's finger nail utilizing a targeting mechanism.

Additionally, the device 10 includes a means to trigger preprogrammed movements of the components of the device 10 while simultaneously outputting audio.

The first embodiment of the device 10 also includes a means to use RC components and to control and direct movement of the linkages and a user directed polishing pattern.

The first embodiment of the device 10 further includes a means to adjust the hand rest 20 in accordance a user's preference and to adjust linkage movements accordingly to facilitate accurate polishing.
